Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

Hoe worden nachtruimtes verbeeld, geproduceerd, ervaren en verteld door migrantengemeenschappen in Europa? Dit onderzoeksproject onderzoekt deze vraag in acht Europese steden: Aarhus, Amsterdam, Berlijn, Cork, Galway, Lissabon, Londen en Rotterdam.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

In 2009-2010 ontstond in het westerse discours het idee van een meer ‘assertief’ China, een opvatting die China krachtig van de hand wijst. Niettemin is, vooral sinds Xi Jinping in 2012 aan de macht kwam, duidelijk dat China zijn lang gehanteerde buitenlandse beleidsdoctrine van ‘een lage profilering…

Why do sexual violence policies still fail to systematically address men and masculinities, when the need for cultural change among men has been central in public debates since #MeToo?

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

The dissertation offers new tools and insights to computation and modelling of topological phases, with an emphasis on the aperiodic setting.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.
